Roundtrip reservations are Zipcar's most common trip type. Below is some basic information on how roundtrip reservations work.
Extending Your Reservation
Provided that another member does not have a reservation immediately after yours, you can extend your trip using the mobile app or by texting.
If the car isn't available, you'll need to return on time as there is someone after you has reserved the car.
Returning Your Zipcar
To end your reservation you will need to return your Zipcar to its home location, which is the same spot where you picked it up. In select cities, you can book one-way trips and drop-off your Zipcar at a different location.
